TOBACCO-PIPE.

SPECIFICATION forming part of Letters Patent No. 246,249, dated August 23, 1881.

Application filed J une 17, 1881.

To all whom t may concern Be it known that I, J Aeon H. VAN HIPER,

of Newark, in the county ot Essex and State of New Jersey, have invented a new and useful Improvement in Tobacco-Pipes, ot' which the following is a specification.

The object of this invention is to prevent the entrance of nicotine and essential oils of the tobacco into the mouth of the smoker, and to retain them in the pipe-stem.

The invention consists of a sectional pipestem whose two central sections have large bores or chambers for the condensation ot' the nicotine and essential oils, and are coupled together with a couplingnut ot' comparative small bore, provided with reduced terminal central bosses, that serve to retain the condensed oils in the pipe-stem, said nut being inserted into the opposite ends ot' the central sections, all of which will be hereinafter described.

The drawing represents a vertical sectional elevation ot' the improved pipe-stem.

In the drawing, A A represent the two central sections of the pipe-stem, bored or chambered out as much as possible consistent with strength, as shown at c a', respectively, and having each end internally screw-threaded, as shown at b Z1', respectively.

B represents the screw coupling-nut provided with a central boss, c, on each end, and a small bore, d, extending` through its entire length and through said bosses c. A ringor annular rib,f, formed centrally around the nut B enables the operator more readily to turn said nut B. This nut B is screwed into the opposite screw-threaded ends ot' the sections A A', as shown.

In the chamber c a piece ot' sponge, g, is preferably inserted, for condensing and holding the oil, Sac., from the smoke passing` through it.

The lower section, U, of the pipe-stem is inserted into the bottom of the section A', and has a cork envelope, C', upon which the pipebowl (not shown) is designed to be tted, and upon the upper end ot said section C is a central tubular extension, h, that forms an annular chamber in the sect-ion A', for the retention of (No model.)

the condensed tobacco-oil, thereby preventing1 it from iiowing into the pipe-bowl.

` Into the top of the section A the pipe-section D is inserted, and upon thisis ttted the mouthpiece E, as shown.

When in smoking a pipe the stem is held in the usual upright or slightly-inclined position, the major portion ot' the nicotine and oils will condense in the chamber a, because, being farther away from the pipe-bowl, (not shown,) the said chamber a is cooler than the chamber cf, and beca-use the smoke has become cooled in being drawn through the bore d ofthe coupling-nut B, andthe condensed nicotine and oil, condensing in said chamber a, will gradually deposit on the upper end of the nut B, but will be prevented from iiowing down through said nut B into the pipe-bowl (not shown) by the upward-projecting boss, c.

At any convenient time the pipe-sections A A may be uncoupled, and the condensed oil and nicotine be removed.

The sponge g serves as an auxiliary condenser, but may be dispensed with at the option of the smoker.

The coupled sections and nut A A/ B may be inverted from their present positions, and the positions ot' the sections C D reversed, in which case the present lower boss, c, will become the upper one, and serve the same purpose, and the chamber a serve as a condensing-chamber. Hence it will be seen that in effect this improved pipe-stem is a doublychambered reversible stem.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- In combination with the central chainbered stem-sections A A', provided with end sections, C'D, of the coupling-nut B, provided with end bosses, c, anda small bore, d, extending` through its entire length and through the said bosses, substantially as and for the purpose set forth.
